IMPROVEMENT IN CANE-SHAVING MACHINES.

Specification forming part of Letters Patent No. 210,945, dated December17, 1878 application filed August 26, 1878.

To all whom it may concern:

Be it known that we, CHARLES L. JONES, J. W. SMITH, and H. H. ADAMS, ofGardner, in the county of Worcester and State of Massachusetts, haveinvented a new and Improved Cane-Shavin g Machine, of which thefollowing is a specification:

The strands of cane used for cane-bottom chairs are shaved and edged tofit them for use by knives while the cane is passing over a cylinder andunder a pressure-roll. The cane passes through between two circularknives that are turned by hand to bring a new part of the knife-edge tothe cutting-point when the edge dulls. The devices heretofore made useof to turn the knives are expensive to manufacture, and the feed has tobe stopped while the knife is turned.

The object of our invention is to construct a canesplitting machine thatwill permit of changing the knives without loss of time, and also tomake the knives adjustable according to the size of the cylinder.

Our invention consists in a toothed pinion upon the stud that supportseach knife, and a worm, which may be turned to operate the gear an (1turn the knife. Each knife is mounted near the end of an arm that ishung upon a pin and the arm mold and held in position by a cam on anarbor, so that the knives may be adjusted to and from the cylinder, tocompensate for wear of the cylinder and to regulate the width of strandthat is cut.

In the accompanying drawing,Figure l is an elevation of one knife andits supporting and adjusting devices. Fig. 2 is a longitudinal sectionof the same at the line m :19. Fig. 3 is a cross-section at the line 3y.

Similar letters of reference indicate corresponding parts.

a is a casting that is to be attached by bolts which pass through theslots 1) b to a saddle (not shown) which is attached to a frame inproximity to the cylinder. There is to be a casting, a, attached at eachside of the cylinder, (shown by dotted line 0 in Fig. 1,) so that therewill be a knife at each side.

(I is an arm, attached at one end to the casting a by a bolt and nut, e,which bolt passes through a slot, f, in casting a, so as to permit thelength of the arm d to be adjusted. is a plate, attached to the castinga by screws h, and lapping upon the arm (1 near to its outer end, tohold said arm to the casting.

i is an arbor, held in a hub, k, on the face of the casting a by ascrew-pin, Z. m is an eccentric-pin formed on the inner end of the arbor'i and entering a slot, at, in arm d. 0 is a hand-wheel on the outer endof 1'. By turning the hand-wheel 0 the eccentric m swings the arm at ineither direction on its pivot e. p is a circular knife, attached to theouter end of arm (I by a stud-pin, q, that passes through the sleeve r,secured in an arm, d, on which sleeve the knife p turns. The face of thearm 01 is cut out around the sleeve 1' to form an annular cavity for asmall gear, .9, that is placed upon the sleeve 4', and is connected toknife 19 by a pin, t, so that the knife and wheel 8 turn together. a isa worm-shaft, fitted in the end of arm 01, and engaging with gear 8.This worm-shaft it extends beyond the end of arm (Z, and has an enlargedend, as shown, whereby it may be turned to revolve the knife 8, andbring any part of the cutting-edge to the cutting-point.

The cane passes over the cylinder 0, that is the thickness of thestrands to be cut, and be heath a pressure-roller, o. The position ofthe knives p at each side of the cylinder is such that the cutting-pointis on a line from the center of the cylinder 0 to the center of o. Theoperator catches the strand with the left hand, and the right hand is atliberty to oper ate the worm-shaft a and turn the knife on its stud,when it dulls at one point. This may be done at any time withoutstopping the feed or delaying the work. 10 is a guard for guiding theedgings as they are cut off. It is attached to a projection from arm (Zby a screw, a, so that one edge rests upon the knife The swinging arm dpermits the adjustment of the knife by the cam or eccentric m to lowerthe knives as the cylinder 0 wears smaller. It also allows the width ofstrand that is cut by the knives to be adjusted quickly and accurately.

We do not limit ourselves to the exact details of construction setforth, as they may be varied without departing from our invention.

v The cylinder 0 and rollers u and 'v are of the character generallyused in cane or rattan Working machinery, and the knife-supportingdevices are adapted, in the form shown and described, for attachment toanj of the wellknown cane-shaving machines. I

Having thus described our invention, we claim as new, and desire tosecure by Letters Patent- 1. The circular knife p and adjustable swinging arm (1, in combination with the casting a of a cane-shavingmachine, substantially as described. a

2. The circular knife 1), cog-wheel s, stud q,

sleeve 7', and pin t, in combination with the worm-shaft to,substantially as and for the purpose described.

3. The arbor i, provided with the handwheel 0 and the cam n, and securedto the hub is of the casting a by the screw l, in combination with theadjustable swinging arm d, substantially as and for the purposedescribed.
